In terms of tickling, my midsection is probably the most ticklish places on my body(aside from feet). I haven't been tickled much in my life am am not toned(yet) but I always felt those who are lean/muscular made great tickle fodder. I figure less fat makes you feel it more(particularly for the belly), and and it's a sight to behold on female lees imo. What instances of this kind of tickling have yall seen, or have you been on the recieving end?
